Description:
Solar energy belongs to clean renewable energy sources. There are a lot of transformation methods of solar energy into another kind of energy. The direct transformation of solar energy into electrical energy by means of photovoltaic cells is one of the possibilities. The aim of this paper is to describe single types of photovoltaic systems and possibilities of their applications. and Solární energie patří mezi čisté obnovitelné zdroje energie. Existuje mnoho způsobů transformace solární energie na jiný druh energie. Jednou z možností je přímá přeměna solární energie na elektrickou energii pomocí fotovoltaických článků. Předmětem tohoto příspěvku je popis jednotlivých typů fotovoltaických systémů a možnosti jejich aplikací.

Description:
Solar engine is discussed as integration of solar collector with linear heat loss and Curzon-Ahlborn engine is considered. This simple endoreversible model is used to discuss some applications of results of endoreversible heat engine in the field of solar engine. Optimum operating temperature of the solar collector and relevant maximum overall efficiency of solar engine is calculated, the results being compared with those by the models where Carnot and Curzon-Ahlborn efficiences were used. Conclusions obtained for endoreversible model are used for simple optimal design of solar engine. The size of heat engine for a given solar collector is optimized. The investment costs of solar collector and heat engine per unit of output power are used as optimization criterion. and Obsahuje seznam literatury
